Definitions

  • the present invention relates to a watch.
  • This watch comprises a housing defining an interior volume in which is disposed a movement having at least one function.
  • the housing comprises at least one opening in which are arranged means for controlling said at least one function.
  • the housing comprises a telescope mounted movably on the housing and having at least one cam arranged to act on said control means when the telescope is moved.
  • the invention relates to a chronograph control device with two pushers which overcomes the aforementioned drawbacks of the prior art namely to achieve two-button chronograph control device whose sealing is improved and more reliable over time.
  • the invention relates to the two-push chronograph control device cited above which is characterized in that said cam is rotatably mounted in said housing and in that the control means comprise at least one mounted pusher. movable in said housing substantially perpendicular to said cam.
  • control device allows a new actuation allowing improved sealing.
  • FIG. 1 On the figure 1 is shown a sectional view of the watch 1 using the mechanism according to the present invention.
  • This watch comprises a housing 2 in which is located a mechanical movement 6.
  • the movement 6 of the watch is of the electronic type.
  • This movement 6 includes various functions such as a chronograph function or minute repeater intended to be controlled by the control device according to the present invention.
  • a chronograph function or minute repeater intended to be controlled by the control device according to the present invention.
  • an example of a control device for a two-stroke chronograph function will be taken as an example.
  • the watch 1 thus comprises a housing 2 formed of a substantially circular middle part 3.
  • This housing 2 is closed in its lower part by a bottom 5 and in its upper part by a glass 4.
  • the middle part 3 has a shoulder at its part superior so that a telescope 7 can be mounted rotatably on its top.
  • the middle part 3 and the bezel 7 are arranged so that a hollow space is created between these two parts.
  • the watch 1 comprises a control system with two pushers using the telescope 7 as interface between the user and the movement 6.
  • the middle part 3 comprises two openings 8 located in its flanks and opening at the level of the empty space between said middle part 3 and the bezel 7.
  • These openings 8 are of any shape, preferably of simple shapes such as a circle or a rectangle.
  • These openings 8 are located vis-à-vis the organs of the movement 6 controlling said chronograph function.
  • the two openings 8 are located at the positions indicating 8h and 10h as usual.
  • the opening at 8 o'clock is located opposite the control to activate the chronograph function while the opening at 10 o'clock is located opposite the reset command of the control. said chronograph function.
  • a pusher 9 In each of the openings 8 is inserted a pusher 9.
  • This pusher 9 is mounted radially relative to the center of the housing 2.
  • This pusher 9 comprises a tubular support pusher 10 driven into said opening 8.
  • This tubular support 10 is intended for receive the main body 11 of the pusher 9.
  • This main body 11 has a section corresponding to that of the pusher support 10.
  • the support 10 has a length greater than that of the opening 8 to improve the guide of the main body 11 with respect to the housing 2.
  • One end of the main body 11 is provided with a pusher head 12 of preferentially rounded shape such as a half-sphere.
  • the free end 13 of the pusher head 12 is separated from a circular groove 14 of the main body 11 so that a spring 15 can be supported.
  • This spring 15 is used during the insertion of the main body 11 into the support 10 so that the pusher 9 returns to position when the pressure exerted on the latter is released.
  • This spring 15 thus bears between the bottom of the groove 14 and the middle part 3.
  • the end by which the main body 11 is inserted has a peripheral groove 16b. Once the body 11 has been inserted, a retention ring 16a is mounted in this groove 16b enabling the body 11 not to leave the support 10.
  • the tightness of the pusher 9 is ensured on the one hand by the fact that the support 10 is driven into the middle part 3 and on the other hand by the fact that one or more seals 17 are situated between the support 10 and the main body 11. These seals 17 are preferably toric type. This combination of means makes it possible to improve the tightness compared to existing systems
  • This telescope 7 is provided with at least one control part comprising at least one cam surface 18 hereinafter referred to as the cam located on the lower part of the telescope 7, that is to say at the level of the space created between the bezel 7 and the caseband 3.
  • the cam 18 and the pusher 9 are preferably mounted perpendicularly relative to one another. other.
  • the bezel 7 comprises a single cam 18 and is arranged so that the cam 18 is located and centered on 9h that is to say between the positions of the two pushers 9. This position is the rest position of the telescope 7.
  • This cam 18 has two ends 19, 20 having an identical thickness and then has a slope as shown in FIG. figure 2a .
  • One end called lower end 19 is located opposite the pusher at 8 o'clock while a second end called upper end 20 is located opposite the pusher at 10 o'clock.
  • a first and a second return spring 21, 22 are used between the bezel 7 and the middle part 3.
  • these two springs 21, 22 are fixed via three anchoring points 30, 31 and 32.
  • a first 30 and a second 32 anchor point are fixed to the middle part 3 respectively at the indications 2h and 4h .
  • An anchor point 31 is fixed on the bezel 7 which, in the initial position, is located at 3 o'clock.
  • the first spring 21 is fixed to the first anchoring point 30 and the anchoring point 31 of the telescope 7 while the second spring 22 is fixed to the second anchoring point 32 and the anchoring point 31 of the telescope 7. .
  • the push-buttons 9 act on flip-flops 40.
  • These flip-flops 40 are the link between the push-buttons 9 and the elements of the movement 6 on which it is necessary to act to activate or deactivate the chronograph function. Nevertheless, it may be provided that these latches 40 are not present and that the pushers 9 act directly on the elements of the movement 6 on which it is necessary to act.
  • the pushers 9 are not mounted radially relative to the center of the housing 2 but in any way.
